Developing efficient and robust free-standing electrocatalysts for overall water splitting is a promising but challenging task. Herein, the N-incorporated Ni nanosheets non-fully encapsulated by N-doped carbon (NC) layer are fabricated (N─Ni©NC). The introduction of N not only regulates size in N─Ni©NC also promotes electrochemical activity metal Ni. Experimental theoretical results reveal that strong bonding lattice activates inert promoting charge transfer between N. In addition, upward shift d-band center induced enhances adsorption intermediates, thereby making as new OER active site together with C. This strategy generating C dual sites introducing greatly accelerates oxygen evolution reaction (OER) kinetics, resulting excellent electrocatalytic performance N─Ni©NC. At current density 10 mA cm
